INCIDENT: Ransomware Attack Forced Ambulance Diversion At Eskenazi Health

Eskenazi Health in Indianapolis went on diversion for more than 5 days, meaning all incoming ambulances were routed to other hospitals after an attempted ransomware attack early Wednesday morning. The attack occurred around 3:30 a.m., and the diversion began at 7:51 a.m. Wednesday. The move affected all of the health system's locations, including Sidney & Lois Eskenazi Hospital downtown. Outpatient clinics remained open. Eskenzai contacted patients with an appointment or procedure that needed to be rescheduled because of the incident. "Monitoring systems responded as they should have and no employee or patient data appeared to be compromised." Tom Surber, media relations coordinator for Eskenazi Health, said in an emailed statement.
